6 Claims.

This invention relates to improvements in shaker conveyers and moreparticularly relates to a new and improvel swivel for permitting onetrough section of a shaker conveyer trough line to deliver material toanother trough section of the conveyer trough line, when positionedlaterally with respect to said other trough section.

The principal objects of my invention are to provide a new and improvedform of swivel for a shaker conveyer trough line including a novel meansfor controlling the path of swinging movement of the laterally swingabletrough section of the conveyer.

A more specific object of my invention is to provide a novel form ofarticulated connection between two trough sections of a conveyerincluding a pair of crossing links pivotally connected at one of theirends to a fixed base and having pivotal connection at their oppositeends with a sliding support means for the laterally swingable troughsection of the conveyer, for controlling the path of swinging movementof said support means.

Other objects of my invention will appear from time to time as thefollowing specification proceeds and with reference to the accompanyingdrawings wherein:

Figure 1 is a plan view of a swivel constructed in accordance with myinvention, with certain parts broken away and certain other parts shownin section in order to more clearly illustrate certain details of myinvention;

Figure 2 is an enlarged longitudinal sectional view taken substantiallyalong line 2-2 of Figure 1;

Figure 6 is an enlarged detail sectional view taken substantially alongline 6-6 of Figure 1; and

Figure '7 is an enlarged detail sectional view taken substantially alongline 1-1 of Figure 1.

In the drawings the embodiment of my invention illustrated is shown asproviding an articulated connection between a driving trough section II!and a driven trough section II of a shaker conveyer trough line, topermit materialto be carried from the driven to the driving troughsection when the driven trough section is positioned laterally withrespect to the driving trough section, so the conveyer may carrymaterial around corners or $0 a pick-up member on the forward end of thedriven trough section may pick up material from the extreme corners of awide room or may be extended along a cross cut or entry at an angle tothe main part of the conveyer, to pick up material therefrom.

The articulated connection between the driving and driven troughsections of the conveyer includes a base I2 adapted to be firmly held inposition on the ground during reciprocation of the conveyer by means ofa plurality of jacks l3, l3 engageable at their lower ends with socketsI4, I4 in said base and with the mine roof at their upper ends.

A connecting trough section l5, having a widened outwardly flaredreceiving end, with curved sides, is reciprocably mounted on said baseon a plurality of aligned laterally spaced grooved rollers IT, ITrotatable about parallel vertical axis. Each of said rollers, as hereinshown, is journaled on a vertical shaft I8. Said shafts are mounted onthe base l2, as their lower ends, and extend through a support member l9mounted on and extending longitudinally along said base and over the topof said rollers. As herein shown, four rollers are provided on each sideof said connecting trough section, although any desired number ofrollers may be provided, and each group of spaced rollers is adapted tohave supporting engagement with a longitudinally extending rod 20,engaging the grooved portion thereof.

Said rods are mounted on and extend along the lower portion of a frame2|, which forms a support for said connecting trough section.

The forward end of the trough section 10 is adapted to be connected withthe forward end of the connecting trough section by means of the usualconnecting bolts 23, 23 extending through abutting eyes 24, 24,

A forward connecting trough section 25, similar to the trough sectionI5, is mounted on the base in forwardly spaced relation with respect tosaid trough section on a reciprocably movable support frame 25. Saidframe has a pair of laterally spaced depending longitudinally extendingrods 21-, 21, which engage the grooves or grooved rollers 28, 28,mounted on a transversely slidable plate 29. Said rollers are mountedbe- .tween the top of said plate and the underside of the upper portionof laterally spaced longitudinally extending support members 30, 3!], onvertical shafts 3|, 3|. Said slidable plate is movable transversely ofsaid base, so the entire support for said forward trough section may belaterally moved across said base. Said forward connecting trough sectionis connected with the driven trough section II by means of the usualconnecting bolts 33, 33 extending through laterally spaced eyes 34, 34.

An intermediate trough section 35 having outwardly curved sides, at itsends, which conform to the form of the forward and rear connectingtrough sections i5 and 25, is provided to bridge the gap between theconnecting trough sections 25 and i5. Said intermediate trough sectionis pivotally connected at its ends, to adjacent ends of said connectingtrough sections and has the discharge end of the connecting troughsection 25 nested in the forward end thereof and is nested within thereceiving end of the connecting trough section it. Said intermediatetrough section bridges the gap between said connecting trough sectionsand also splits the angle between said trough sections, to eliminateabrupt turns from one trough section to the other and to prevent thepiling up of material at the turn.

The intermediate trough section it has a stub shaft 3t secured to anddepending from its bottom and journaled in the frame 25 on a bearing 37,mounted in a bearing sleeve mounted on said frame. Said sleeve extendsthrough a bored portion of said frame and upwardly therefrom through theconnecting trough section i5, forms a mounting for said connectingtrough section on said frame.

The opposite end of the intermediate trough section 35 underlaps theforward connecting trough section 25 and is mounted on a bearing sleevetill, secured to the frame 2% and projecting upwardly therefrom. Saidforward connecting trough section has a stub shaft :23 secured theretand depending therefrom, which extends through a bearing mounted in saidbearing sleeve. The driven trough section ii and forward ccnnectingtrough section 25 may thus be transversely moved across the base i2about the vertical axes of the stub shafts St and d3.

Referring now in particular to the novel means for controllingtransverse .iovement of the plate 253 and the roller support for theforward connecting trough section 25 across the base plate 2, to causethe plate as and rollers to move in the same path as the path ofmovement of the connecting trough section 25, pair of crossing controllinks Q5 and t! are provided. The furcations of the rear bifurcatedend'of the link 66 extend on opposite sides ofa bracket member id,mounted on the base l2. Said link is pivotally connected to said bracketmember by means of a pivotal pin t and extends fromsaid bracket memberdiagonally across said base, and its forward end is pivotally connectedto a bracket member 55, projecting rearwardly from the plate 29, by apivotal pin 52.

The link t? is like the link it, but its bifurcated end portions are soarranged that said link will cross under the link 35, asis shown inFigures 1 and 6. Said link is pivotally connected to a bracket 53, atits rear end, by means of a pivotal pin 5%, and is connected to abracket 55 at its forward end by means of a pin 55. As herein shown, thepivotal pins 5 5 are positioned equal distances from opposite sides ofthe stub shaft 36 and are spaced forwardly therefrom a slight distanceand the pivotal pins 52 and 56 are mounted on the plate 2%} beyond therear end thereof and are laterally spaced the ii" n same distance apartas the pins 55 and E4 and equal distances from the center of the shaft43. Said links, crossing each other, thus form a controlling connectionbetween the base and the plate as, for controlling the path of movementof said plate so it will move about the spaced vertical axes ofconnection of the intermediate trough section 35 to the connectingtrough sections I5 and 25.

While I have herein shown and described one form in which my inventionmay be embodied, it will be understood that the construction thereof andthe arrangement of the various parts may be altered without departingfrom the spirit and scope thereof. Furthermore, I do not wish to beconstrued as limiting my invention to the specific embodimentillustrated, excepting as it may be limited in the appended claims.
